Dear jitsi video bridge gurus,
can somebody please provide some info regard what kind of CPU load should be
expected while running video bridge with lets say 6 parties in the
Would be great to get a benchmark data for various types of HW
configuration, if such available.
Also, what kind of hardware (number of the cores and horsepower) is
recommended to run video bridge to get a "usable" experience.
We still have a number of optimisations pending so that kind of
extensive testing would probably be best in a couple of months or so.
A snapshot of the current state however: I was on a 12 person call
yesterday using the bridge on a VM with 1 GB RAM and a 3.3GHz CPU (one
core), we were running at about 60%. Again, we expect to be doing much
better in a couple of months. Our short term goal is to be able to
host 100+ user sessions on an average VM.
We tried to run the video bridge on the Intel Pentium Dual CPU E2160 @ 1.80
GHz machine and the CPU load we experienced was by far beyond expected.
Running the video conference with up to 4 participants it seemed that each
stream required about half of the CPU power.
This doesn't sound normal, but I don't think we would be analysing
performance before we've finished the optimisations that we have in
When we tried to increase
of participants video started to freeze constantly and few participants kept
seeing only black screen for the other participants video.
This might be due to other things. Make sure that within the $HOME
directory of the user running the bridge you create a
.sip-communicator directory then add a sip-communicator.properties
file with the following line:
And this is just
conference, while our expectations were to be able to run multiple
Yes that's the whole point of doing the bridge but we still have a bit
more work before performance is optimal.
